Riding discontent in the Philadelphia suburbs, Democrats picked up 16 seats between the Pennsylvania House and Senate on Tuesday, besting nine incumbents and breaking the GOP Senate supermajority in a big night for the party that had been whittled down to historic lows in both chambers.

Republicans will keep a majority in both chambers, but they’ll be smaller and missing some of the moderates who formerly thrived around West Chester, Norristown and Media.

From Pottstown to Lock Haven, West Chester to Fox Chapel, election season is now in full swing.

While the much prophesied “blue wave” has a real chance to wash in a new Democratic House majority in Washington DC, it’ll likely crest too low to overturn the 39-seat Republican majority in Harrisburg’s House.

Plenty of GOP seats, especially in the southeast, appear primed for flips. But Democrats need to defend a caucus spread out into places that run red the length of the ballot, while their strategists know that any path, no matter how slim, to an eventual majority needs to include a few tough, uphill fights.
